Everything is acceptable except for Ansys simulation. How annoying! An interesting thing is that when I change the cores used in the HPC settings, I find it seems only 8 cores are working. When I increasing the core number from 1 to 8, the simulation time cost decreases accordingly, but 8/16/32 (logical) cores perform almost the same. The specified cyclic symmetry mode must be the same for all loads defined within a given steady-state dynamic step. Base motion is not implemented for cyclic symmetry models. Cyclic symmetry conditions are applied to the mechanical degrees of freedom in stress/displacement analysis and temperature degrees of freedom in heat transfer analysis.

Hi - what is the correct way to set up a circular waveguide simulation taking advantage of the symmetry (i.e. Apr 30, 2020 · The wedge boundary condition also requires only a single cell between the boundary pairs, whereas the symmetry boundary condition can discretize in multiple cells. This gives a slight advantage to the symmetry boundary condition since a more accurate circular surface can be generated rather than a straight line between the two wedge planes.

Symmetry boundaries are used to reduce the extent of your computational model, they are used when the physical geometry, and the expected pattern of the flow/thermal solution, have mirror symmetry.... RE: Cylindrical Symmetry - Wheel Rail contact - Ansys Workbench 13 flash3780 (Mechanical) 15 Jan 13 19:37 I'd recommend that you take a look at the meshing tutorial which is available in the ANSYS customer portal to get you started with meshing. analysis run time and memory required The lines or planes of symmetry or anti-symmetry in a FE model can be simulated by providing proper restraints to the symmetrical faces or edges. To model symmetry or anti-symmetry, the geometry and the restraints must be symmetric about a plane. The loads must be either symmetric or anti-symmetric. ANSYS Workbench Mechanical supports cyclic symmetry analysis, and makes it easy to simulate with a Symmetry branch in the Outline at the Model level. A user indicates the Low Boundary and the High Boundary for the Cyclic Region of interest. Sep 27, 2016 · The main idea of a symmetry fixture is to run a study on a 1/2, 1/4, or 1/8 portion of your model, while Simulation still thinks that you are running the study on a full model. This can save you a lot of elements and this way it will influence the calculation time. Hello everybody, that´s a simple question: I have a symmetry problem to analisys using Structural Mechanic on Ansys Workbench. I´ve applied a Symmetry function on Design Modeler. Can I visualize the result on the whole geometry? Thank´s in advance Ansys Maxwell Simulation- Torque Fluctuating Thread ... (Sometimes model reduction + symmetry boundary may introduce some issues). Today, 3:51 AM #5 The student community is a public forum for authorized ANSYS Academic product users to share ideas and ask questions. Hello Community, A sample of the bolt-pretension model that I am simulating with Workbench is depicted below: 1. Hi, I am having some difficulty understanding the force reactions in a symmetry plane. I am running a half symmetry model, fixed at one end, displacement BC on the other end - it is a two parts assembly - the model is cut in half in the middle and a symmetry BC is placed on the symmetry plane faces, the BCs are all half symmetric (symmetric loading and geometry). geometric patterns, cyclic symmetry modeling reduces computation time. “We use ANSYS as a virtual laboratory, since ANSYS code is really close to the actual physics. It assures you when something is a good idea — and demonstrates clearly when a design fails.” Benjamin Hagege Assistant Professor University of Technology of Compiègne Vibration ANSYS FLUENT assumes a zero flux of all quantities across a symmetry boundary. There is no convective flux across a symmetry plane: the normal velocity component at the symmetry plane is thus zero. There is no diffusion flux across a symmetry plane: the normal gradients of all flow variables are thus zero at the symmetry plane. Hello everybody, that´s a simple question: I have a symmetry problem to analisys using Structural Mechanic on Ansys Workbench. I´ve applied a Symmetry function on Design Modeler. Can I visualize the result on the whole geometry? Thank´s in advance Feb 14, 2013 · Symmetry : It is used to reduce the computational model in 3D. For example if you have rectangular box then you can model 1/2 or 1/4 by using the one or two symmetry planes respectively. Axis: It is used to model the 3D problem by just taking the one plane and then solving it in the cylindrical coordinates. ANSYS Mechanical - ANSYS Structural ANSYS Professional - ANSYS DesignSpace.

ANSYS 17.0 extends the available methods, including multistage simulation, multi-frequency disturbance and asymmetric geometries, which enable efficient CFD simulation of multistage axial turbines, a blade row subjected to upstream and downstream disturbances, and an aircraft engine fan subject to a cross-flow, respectively. At R14.5 symmetry expansion for non-cyclic analyses is, by default, not enabled. You can, however, do it by enabling beta options (help will say how to does this). Once beta options are enabled, you insert a symmetry branch into the tree (it does not need to contain any actual symmetry regions).
